HARRY B. VAUGHAN, OF LITTLE ROCK, ARKANSAS.

CAR-FAN.

SPECIFICATION forming part of Letters Patent No. 600,814, dated March 15, 1898.

Applioation filed J' 11116 14;, 1897.

To all whom it may concern.-

Be it known that I, HARRY B. VAUGHAN, of Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in Oar-Fans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to automatic ventilating-fans for railroad-cars or other moving vehicles.

A principal object of my invention is to provide efficient means for reversing the driving wheel or fan so that it will operate when the car is moving in either direction.

' may rest on the window-sill of the ear.

The invention consists of a frame having a support or standard from which a hearing or supporting-arm projects and upon which a driving-shaft composed of a tube or hollow cylinder is mounted, in combination with a reversible bracket upon which is mounted a rod or arm, which also. supports a driving sleeve-like shaft, which carries on its outer extremity a driving fan or Wheel.

The invention also consists in other details of construction and subordinate combinations 1 hereinafter described, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective showing my invention as applied to use on a railroad-car, the ventilating-fan part being shown in dotted lines.' Fig. 2 is an elevation, partly in section, showing my invention, the sectional part showing my arrangement of ball-bearings. Fig. 3 is an elevation showing the means whereby I am able to reverse the driving-shaft.

1 is the side of the car; 2,the window-frame of said car; 3, a pillar or support carrying a bearing-rod or projecting arm 4 and a reversible bracket 5. The pillar or standard is supported on a suitable step or shelf 6, which The bracket 5 carries a rod or arm7,which extends, when in use, at right angles to the arm or rod 4 and carries a hollow driving shaft or sleeve 8, the bearing-surfaces between the shaft and the supporting-arm being provided with ballbearings.

9 is the outside fan or wind-wheel. It is $e1'ia1No. 6%,681. (No model.)

mounted upon and carried by the outer end ,on ball-bearing 14, as shown in section in Fig. 2. The bracket 5 is connected with its standard 3 by means of a pivot-bolt 15 and by means of a clamping-bolt 16. By loosening the bolt 15 and removing the bolt 16 the bracket-carrying arm 7, shaft 8, and drivingwheel 9 may be swung around, so as to point in a direction opposite to its original position, when the bolt 16 may be inserted and the bracket clamped in place, the bolt 15 also be ing tightened at the same time.

By reason of' this construction and of the combinations shown and described I am able to reverse the position or direction of the driving-wheel without disturbing any of the other parts of the device, and as a whole I secure a ventilating-fan which operates without jar and friction,thereby obtaining amechanism of efficiency in a very simple manner.

My invention may be applied to the top of a car instead of to the window by means which will be obvious to any mechanic. It will also be apparent that a plurality of fans inside of a car may be operated by the force of the driving-fan through the medium of suitable belts and pulleys. This is so obvious that illustration of its application is deemed unnecessary. Y

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is'- 1. The combination of a standard, a supporting-arm projecting laterally from said standard, a reversible bracket connected with the standard, supportingarms projecting from the bracket,hollow shafts mounted upon the respective supporting-arms, a wind-wheel mounted on one shaft, and a fan on the other and gearing for driving one shaft from the other, substantially as described.

2. The combination of supporting-arms arranged at an angle with each other, tubular driving and driven shafts mounted through ball-bearings on said supporting-arms, a Wind- Wheel on one shaft and a fan on the other shaft and means for driving one of the shafts through the medium of the other, substantially as described.

3. The combination of a standard, a supporting-arm projecting from said standard, a

shaft mounted on ball-bearings carried by said arm, a fan mounted on said shaft, a reversible bracket connected with the main standard, a supporting-arm connected with the bracket, and hollow shaft mounted on ball-bearings carried by the supporting-arm, and a wind-wheel on said shaft, substantially as described.

In testimony whereof I have signed this specification in the presence of tWo subscribing Witnesses.

HARRY B. VAUGHAN.
